I have seen quite a few smoothbores that will shoot well to 100 yards. I do not hunt with a shotgun much anymore, I either use my muzzleloader or .44 mag. I can say with complete honesty though that I have cleanly, one shot, killed more than one deer over 100 yards with my 20 ga. Browning BPS upland special. Smoothbore, improved cylinder choke tube, vent rib barrel with bead, no sights, using Activ slugs. I still have about 10 boxes of the Active's and would buy more if they were still made. Anyways, lots of guys have scopes on smoothbores and like them. You are right, you do not really have to jump on the rifled barrel, high dollar scope bandwagon unless you choose to. Now on the other side of the coin, a quality rifled barrel, cantilever scope, and those new Hornady slugs are making 200 yards shots possible if your gun is sighted in for that kind of range. They certainly do not give those slugs away though.
